| 摘 要： | 本文建立了两跨简支梁桥和五跨多跨刚架桥两结构模型，针对限位器的种类、刚度、强度、安装位置，输入地震动等进行了大量工况下的数值模拟研究。研究表明限位器与柱（框架）的刚度比在0.5-2之间较优。将现有的限位器设计方法应用于两算例结构，对现有限位器设计方法进行了比较研究。

| Abstract: | In this paper, a simply-supported bridge and a multi-frame bridge model are established. According to the variations of the type,stiffness,location of restrainers and earthquake-input etc, the digital simulated studies are done and the results show that the ratio of stiffness between restrainers and pier(frame), ranging from 0.5 to 2, is better. The research on applications of the current design method for the two examples of structures is presented. |
